Why do the 360 graphics look mediocre ?

Q. I have a 19" widescreen HD LCD monitor. and I'm that impressed by the 360 graphics.

A. My guess is because you may be a computer gamer. The 360 and the PS3 have finally caught up with the graphics that a decent PC has had for quite some time. I wasn't impressed at first either, but that was before I played Gears of War. You also have to remember that game developers have not learned the full potiential of the system yet and as time passes the games will get better and more impressive.

What are the pros and cons of LCD vs Plasma vs Rear projection?

Q. I also heard there is no noticable difference between 1080i vs 720p when your set less than 50"

A. LCD - This is the everyman HDTV. Its mass produced, cost effective, low on power consumption, and just what people "know." LCD monitors in computers make it a more familiar product for many. Its SD playback tends to be a bit sharp/crisp; think the evening news (this isn't good vs bad, this is personal taste). Its colors tend to be a bit more muted (again not good vs bad, just taste). LCDs have a matte finish for the viewing surface (the edge around it can be glossy though depending on model).

LCD's are inherently bad with motion playback. The suffer from motion blur (ghost trails). This is why you see "better" ones advertised with 120Hz or 240Hz refresh rates. The improved refresh rates are an attempt to overcome that inherent flaw.

LCD's will give you weaker blacks, colors, and contrasts on the whole. This is why you see the proliferation of the LED LCD. That technological step alleviates those LCD problems.

Plasma TVs inherently give you better blacks, colors, and contrast. They are also inherently strong in motion playback as their refresh rate is near instantaneous (like a CRT). Plasma colors tend to have more pop to them (not good vs bad, just taste). Plasma SD tends to be a bit softer (think Hollywood films); again not good vs bad, just personal taste.

Plasmas should be conditioned though. For the first 100-200 hours of operation you want to keep the contrast and brightness cranked way down. Then optimize and enjoy. This isn't necessary persay, but most "nerd" consumer groups will tell you to do it for paranoia sake.

Plasma TVs are a shiny finish though, so in rooms with light control problems that finish can create reflection problems. Plasma technology on the whole does use more power than LCD. But not all models are made equal, so one must do some homework. And worst case scenario, a "very bad" Plasma TV would likely only cost you $40 more per year in electricity bills (and again not all models are made equal).

Plasma myth (1) - They experience burn-in. This is inaccurate, those days are gone. Just condition the gasses and then use it as normal and you're fine. Also, the better sets have built-in features to prevent this (on top of the technology just generally being better now than say 5 years ago).

Plasma myth (2) - They have short life spans. This is another inaccuracy. Most are now rated in the 60,000-100,000 hours range. At 8 hours a day 365 days a year that would mean a life of 20-30 years. So do you think you'll still want/own the same TV in 15 years, let alone 30?

Plasma myth (3) - They won't work in high altitude because of problems for the gasses. This is again no longer an issue. Current Plasmas can be purchased and used in mile high Denver, and above, so you'll be fine where ever you are (unless you're living in the Himalayas).

720 vs 1080 - There is no set size on when it matters. Typically though its though that anything under 40" definitely doesn't show any of the advantages of 1080. 40" - 50" is the grey area where some argue it matters and others say maybe a bit or not so much. 50" and above you definitely want native 1920x1080 resolution for your TV, as the advantages will become noticeable.

Damn almost forgot... DLP Rear Projection. The image quality, on all levels, is fairly close to Plasma. It would be at par with it if it wasn't a dying technology. Mitsubishi is the last developer of the technology after Samsung recently announced they were giving up on it. So Plasma is just getting more R&D and advancements than DLP. That said though DLP is still a rock solid image.

Its often joked that DLP will be the last TV you ever own. That refers to the expectation that the TV will still work until its actually physically falling apart (decades). But the bulbs in it need to be constantly replaced. Depending on the bulb and your TV usage, it could last anywhere from 1 year to realistically 4 years. Replacing is something you can do on your own easily enough. A new bulb though costs $200-$250 or higher. Also, some sets have air filters that you should clean every month or two. So there is certainly an inconvenience factor in owning the sets.

How do I play NTSC PS1 games on my PAL PS3?

Q. I have a few PS1 NTSC games that I wanna play on my PS3 (I have a modded PS1 but it isn't as clear on my HDTV.) Everytime I stick a disc, the PS tunes me about the regional codes and stuff, how do I prevent that? P.S... THESE ARE ORIGINAL GAMES, NOT COPIED OR FAKES.

A. HD on PS3 have no PAL/NTSC problems but if you use the regular composite cable then there will be problems.

HDMI usage also must be complemented with HDCP compliant HDTV or any HD display such as PC Monitors/LCD's or no display at all.

Using Component cables gives you resolution up to 1080p on games but only max 720p on movies.

(Using Regular Composite cables supplied with PS3) PAL games will not run on NTSC PS3 via regular NTSC TV

(except for PAL games that are programmed by developers to support both PAL and NTSC signals) and vice versa.

Hope that answered your questioned !

LED or LCD monitor - which is better for the eyes?

Q. Hi,

So recently I have been experiencing eye-strain but I have to use my computer (I'm a freelance front-end web developer). I currently have a monitor that is a few years old. It's a Dell 20" Flat Panel Display LCD monitor (Model no: SP2008wfP). I'm wondering if an upgrade would improve it even slightly? If so which monitor should I get;

- Samsung S22b150n 21.5" LED Monitor

or

- Samsung S24b150b 24" LED Monitor

A. Personally when choosing monitors I would go with a LED over a LCD just by preference.

Going in deeper though any monitor is no better than any other when it comes to eye damage, as none actually cause eye damage. Unless your using a Radioactive screen (which in that case you've got other problems) your fine.

What you really want to focus on is the power, and managing the nature of the lighting efficiency.

Hope this helped.

Why do fonts look so awful on Firefox in Ubuntu?

Q. Do the Ubuntu devs use the terminal to surf the web? Why do fonts look so awful on Firefox while using Ubuntu with a resolution of 1440x900?

I've tried adjusting the fonts in Firefox and they still look terrible. Why can't Ubuntu developers make nice looking fonts, such as the perfected fonts in Windows?

A. Your problem isn't the fonts - the fonts are perfect, but the display isn't right. You can copy all of the fonts from an XP and a Vista installation - I did this and put them into /usr/share/fonts/ in a folder called mscore - then ran fc-cache and then tried a few out. The only one really worth keeping is Trebuchet - I use that as a font for my conky - digital time display at the bottom of the screen. The other fonts aren't an improvement at all, it's simply the screen rendering - 96dpi or 97dpi? check it out.

You're using quite an old version - 8.04 is very old now. With Jaunty, the Xserver sets itself up - it adjusts to the correct dpi of your monitor. I was extremely impressed.

It now looks much better than Windows.

If you want to find out, I think perhaps your settings are messed up. You can test my idea by doing the following:

Open Nautilus browser (ALT + F2, type 'nautilus', hit enter)

press CTRL and H to get hidden files showing.

Right click, make a NEW folder, name it AAA.hidden

Select all of the documents and folders you see with a name starting with a '.' - like '.bashrc' and stuff, drag them into the folder.

Now log out from your desktop, or just restart. You should come back to a basic gnome desktop with fonts perfectly adjusted.

If you don't - then I strongly suggest that you simply get a Jaunty installation disk and install. You messed it up somehow - because believe me, my fonts are perfect and when I reboot to Windows to play games, they look NASTY.

If you use an LCD, just check - it should be automatic, but in Appearance-fonts you should be set up to use Subpixel smoothing with maybe 96dpi (for my monitor) with slight hinting, and select rgb/bgr/vbgr - for my HP it's RGB.

Honestly, Firefox and all the other browsers and applications look far better than they used to look even with Ubuntu 8.10 now because the set up is automatic on installation!!!


Okay - update - you're using 8.04, probably a pre-install right?

Run 'partition editor' and write down details of how your partitions are laid out. If possible, have a separate partition for all of your personal stuff, move it there.

You really should look to format ext4 (sooo fast and silent compared to ext3 - I copy at 50MB per sec now, instead of 22mb/sec with NTFS or ext3, and a full filesystem check takes 10 seconds, instead of ten minutes).

So move as much stuff you need to a separate partition. Download and burn a Jaunty CD (www.getubuntu.com) and boot that. You can create a USBstartup disk from the system menu - this is so much cooler and faster than a liveCD (silent, fast, and can remember settings) - then install.

Set yourself a root partition, maybe 15 up to 20GB (it is hard to make it fill up past 7 or 8GB to be honest) then a /etc partition, only small - less than 4GB, then the rest could be home - but at least 50GB maybe. Then if you're dualbooting you can use NTFS for a shared storage partition (but it's much much faster if you use ext4 for EVERYTHING - my boot up time is 25 seconds and I only hear a single click if I listen carefully to the HDD)

I'll bet if you boot from USB your monitor will look amazing - so install Jaunty, it's so much better than 8.10 and for me, I found 8.10 was much much better than 8.04.

I started with 7.04 - and really, you have NO idea just how massive the improvements are - they come only a few months apart - 9.04 is like TEN years ahead of 8.04.

Go for it - honestly, I had lots of problems with 7.04 and 7.10 - quite a few with 8.04. just one with 8.10 and so far, with 9.04 everything seems to be automated, driver downloads - everything was soooo smooth, it's like a new operating system (nothing like 8.04)
